Where is Crt unit in Delphi

In Delphi, the Crt unit is part of the older Turbo Pascal environment and provides functions for handling text-mode input/output in console applications, such as controlling the cursor, reading key presses, and setting text colors. The Crt unit is not included by default in modern Delphi versions, as Delphi has shifted focus to GUI-based applications. However, you can still use the Crt unit in Delphi if you are working with console applications and need basic console I/O functionality. You may need to manually include it by referencing legacy code or adding it from compatible libraries.
